HOOP-NAILING MACHINE.

SPECPICATION forming-part of Letters Patent No.1295,5l6, dated March2.5, 1884.

Application filed January 18, 1884. (No model.)

To @ZZ whommay concern.'

Be it known that I, ANDREW C. BATCHEL- LER, a citizen of theUnitedUnitedStates, residing in Bay City, in the county of Bay .andState of Michigan, have invented a new slipped off the form is ready tobe driven upon the barrel; and the object of my nimprovement is toreduce the labor of manufacturing barrels by providing a form which mayeasily be adjusted to conform to the size of different barrels, and lIattain this object by the mechanism illustrated in the accompanyingdrawings, in Wliicli- Figure l shows a vertical section of my improvedhoop-former- Fig. 2 shows a transverse section of the same at the dottedline m fr.

Similar letters refer to similar parts in all the views.`

a and b represent two parts of a circular form, the circumference ofwhich, when the parts are connected together, is about or nearly thesame as that of an ordinary barrel. These parts a and b of the form areunited together at f and h by the bolts c. A portion at one end of thisbolt cis provided witha right-hand thread and a portion of the oppositeend with a left-hand thread, while between the threads and midwaybetween the ends of the bolt c, and rigidly attached thereto, is the nutd, and the parts a and b of the form are provided with a suitable threadto engage with that on the bolts c. So that when the bolts c are inposition to connect the parts a and b together,

as shown in Fig. 1, by turning the bolts c in one 45 direction thecircumference of the form is enlarged, and by turning the bolt-s c inthe opposite direction the circumference of the form is diminished, andby this means an accurate adjustment of the form is obtained to conform5o to the exact size of the barrel to be hooped, and as the size of thebarrels manufactured is often changed, a corresponding change is quicklyand easily made in the size of the form as shown. y

The usual manner of nailing the hoop is to place the hoop around thebarrel somewhat above the position it is designed to occupy, andoverlapping the ends and holding them together bythe hands; it is raisedoff the bar- 6o rel and placed ou a suitable solid piece or anvil, andnails or staples are driven into the overlapping parts, and the hoop isthen placed Von the barrel and driven down to itsproper position. Muchof this labor is avoided by 65 the use .of my improved form, as when theform is adjusted the hoop is placed thereon, and the overlapping partsnailed together. It is then placed on the barrel and driven down to itsproper position. 7o`

Having fully described my improvement, j what I claim as new, and desireto secure by Letters Patent, is I In a hoop-nailing machine, a circularform consisting of the semicircular parts a and b, 75 joined together attheir ends, as described, by

`the bolts c, which are provided in their cenl ANDREW' C. BATCHELLER.
